How to Troubleshoot an E-Z-GO Speed Controller

E-Z-GO golf carts are used by golfers to travel between holes on golf courses. The speed on an E-Z-GO golf cart is controlled by a device known as a governor. If the golf cart runs too slow or seems to sputter, it may be because either the battery has become low or because the governor needs to be adjusted. It takes about 30 minutes to troubleshoot and make adjustments to the E-Z-GO golf cart.

Instructions

    • 1

      Lift the E-Z-GO battery cart seat to access the battery.

    • 2

      Set the multimeter to the voltage setting and place the meter's leads to the corresponding positive and negative battery terminals. The reading should be 12 volts. If it is not, the golf cart battery should be charged or replaced. Also, check the battery cables to make sure they are tight. If they are loose, tighten them with an adjustable wrench.

      Locate the governor on the top center of the engine. It will be a T-shaped piece next to the carburetor.

      Look to see if the governor has shifted to the left, away from the carburetor. The closer the governor is to the carburetor, the faster the cart will travel. If it is too far left, loosen the retaining nut holding the governor in place, then slide the governor toward the carburetor. Tighten the retaining bolt and then test out the cart.
